1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectiveTo estimate the effect of adjuvant chemotherapy (AC) on the prognosis in cervical cancer patients with intermediate- or high-risk factors after radical hysterectomy (RH) compared to that for adjuvant radiotherapy (AR).

methodsThe Embase and MEDLINE databases and the Cochrane Library were searched for published studies comparing cervical cancer patients who received AC with those who received AR after RH. The endpoints were patient oncologic outcome. Random-effects meta-analytical models were used to calculate the pooled estimates of the effect of AC on mortality/recurrence.

resultsTwo randomized trials and eleven observational studies (AC, 942 patients; AR, 1,721 patients) met our search criteria. There were no significant differences in mortality and any recurrence between two groups. The results for distant recurrence favored the AC group (pooled odds ratio: 0.69; 95% confidence interval: 0.54-0.88; p=0.03). In subgroup analyses (for study design, histology, indication for adjuvant treatment, AR type, AC type, and lymph node metastasis), there was no significant increase in mortality and recurrence for AC compared with that for AR.

conclusionCompared to AR, AC showed similar survival outcomes in cervical cancer patients undergoing RH and also appeared to reduce the risk of distant recurrence.
